With the Open Call announced, lets talk about Power and Vision. In Galaxy
Pirates I have things that derive their power from Chemical, Mechanical and
Electrical sources, this mainly matters if someone is trying to deprive you of
that power like when a Solar Flare fries your electronics.

This matters for the Open Call because I have found Darkvision equivalents
for all three;

Chemical Eye Drops, likely to be priced like a Potion and dropped in the
eyes not imbibed.

I can't find the link now, but basically a group had an idea to create Night
Vision contact lenses by using thin film Prisms to alter the frequency of
incoming light into visible spectrum frequencies.

A different group had an idea for a Graphene based Infrared sensor to make
Night Vision contact lenses. The Graphene solution does require a small
electrical component.

One assumes that either of these approaches could be used to make Glasses or
Visors as well.

Night Vision Goggles

Night Vision Goggles, and related technologies have been around for a while.

The idea behind the three power sources is if someone had an Electromagnetic
Pulse (EMP) go off near all three of these Darkvision replacements only the
traditional Goggles might actually be fried. This will slightly complicate your
resource management, the best mix of weapons and gear might not always be the
most high tech.

In the Future part of the SRD you will find references to Gadgets like
Weapon Gadgets including as Scope, Scopes used to be Equipment in Modern.
Scopes can be both Mechanical (traditional optics) or Electrical (video or
holographic). I haven't found a Chemical basis for a weapon scope yet, there
are liquid lenses that flex, but are still Mechanical Optics. I had an idea for
an All Ranges scope using a Light Field camera and an array of Micro-Lenses
which can be paired like Bluetooth to a Display device on the weapon, in your
Helmet, on your Glasses and allow you to shoot around corners if need be. Third
big paragraph from the bottom in the discussion of why weapons needed
updating.

In a breakdown of today's robots and the Future robots of 2004 I decided
that a lot of technologies that were parts of a piece of gear in the SRD needed
to be broken up. So your Robot/Drone Controller could be paired to any kind of
communications technology, a drone with a camera could be paired to any Display
you have Helmet/Goggles/etc. So if your Electrical device needs to talk to
something, assume that it can be paired to any other Electrical device.

The only other thing to think about is Laser Sights and Scopes in the SRD
both basically replace Feats (Point Blank Shot and Far Shot) from the same
sources. The Robe of Eyes replaces two Class Features (Uncanny Dodge and
Improved Uncanny Dodge) you might look into ways these devices can do what they
are supposed to without invalidating a caracter Character class or character
concept's reason for being.
